How to restore your Mac to factory defaults

We’ve all ran into issues with our Macs, Yosemite has issues with upgrading and networking from feedback we’ve gotten from customers and have seen personally; and if you want to roll back to Mavericks, I suggest doing a clean install. Some might even find this handy before selling your existing Mac after getting a new one.
